' This inventionrelates to paper clips or fasteners.

It is a general object of the invention to provide a temporary securingclip of simple and effective construction; which can be securely clampedin holding position; which is easily operable to engage and disengage abunch of sheets, and which has a gripping meansand a clamping deviceoperative thereon to accomplish a setting of the'gripping on interposedsheets. 1

A further object is to provide a double jawed, self-opening grippingmeans and an inseparable, resilient, closing vice therefor, and which iscapable of adaptability to variant thicknesses of stacks of sheets.

An important object is to provide a safety paper fastener of such formand construc tion that it will be snug up to an edge of interposedsheets so that these may be filed without disadvantageous obstruction.

Another purpose is to provide'a reliably adhering or safefastener whichis of low cost; of light weight, is substantial in strucv v Figure 2isan ture and does not destructively'lacerate the gripped paper sheets.

There are additional objects, advantages and features of construction aswill be made *manifest in the ensuing description of embodimentsherewith illustrated; it being understood that modifications,variations, and adaptations may be resorted to w1th1n the scope,principle and spirit of the invention as it is hereinafter claimed.

The. fastener consists of two principal pieces one of which includesagripping means Figure 4 is a plan of a fastener with a and the other anassociated vise to close the gripping means.

, Theigrippingmeans ing an upper leaf 2 and a lower leaf 5 which areofone piece of spring sheet metal folded medially to bring the leaves 25into opposed relation and normally s'pringing'to an open,

divergent position, Figure 3. The leaves may be perforate at 6, Figure4, or'imperforate as in Figures 1, 2, and 3. The bow of the fold 7provides for a hinged efiect during closing of the leaves 2 -5.

The leaf 2 has an upwardly embossed crescent ridge 3 and opposed to thisis a similar ridge 4 on the lower leaf 5; these ridges tending totelescope when the leaves are brought together and therefore taking gripon interposed a clamping device in the form of a staple shaped vise witha pivot bar 11 is turnably' and perpendicularly pivoted inthe fold 7 sothat its jawjs 1213 can be swung around and onto the ridge 3 and thebottomleafrespectively; the distance between the jaws 129-13 ward eachother as thejaws are forcedonto the leaves, as in Figures 1- and"7. Theopen rolled fold. 7 forms an open-ply, back-bone ports for thediametrically disposed pivot 11. While the'jaws1213 of the vise arestifi enough to hold the leaves closed on a stack," i the jaws arepreferably formed of spring wire and may yield to compensateforever-thick stacks of sheets; If'desired the top jaw 12 may have ahump or loop ll for finger purchase.
